Sit facing the cable machine with a straight bar attached to a low pulley. Grab the bar using an overhand (reverse) grip, about shoulder-width apart. Rest your forearms on your thighs so that your wrists hang just over your knees.

1. Point your knuckles down, allowing the cable bar to stretch your wrists fully into flexion.
2. Slowly curl the bar upward by pointing your knuckles toward the ceiling, contracting the forearm extensors.
3. Curl your wrists as high as possible without lifting your forearms off your thighs.
4. Slowly return the bar to the stretched position to begin the next repetition.
